Specification of Letters Patent. Patngntedl Nov. 23, 1915..

Application filed April 17, 1915. Serial No. 22,198.

T 0 all whom it may concern:

Be it known that we, JOHN E. FREY and THoMAs F. BERRILL, citizens of the United States, and residents of New York, borough of Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Sheet-Metal-Door Construction, of which the following is a specification.

Our invention relates to doors and has particular reference to hollow steel doors and sashes and the panel construction therein, but it will be understood that some of the novel features of the invention are applicable in panel construction generally.

The primary object of the invention is to provide novel means for joining the parts of the door together and for holding the panel in place. lhe interlocking parts are greatly simplified and consequently they are less expensive to make and assemble. The construction of the glass molding and glazing strip which holds the glass is a novel feature. The means by which the parts are fastened together without the necessity of rivets, screws or bolts provides a cheap and eflicient method of construction.

The above and other objects and the novel features of the invention will appear from the following description taken in connec- Figure 1 is a perspective view of a door embodying our invention; Fig 2 is an enlarged vertical section of the door, taken on the line 2-2 of Fig. 1 with parts thereof broken out and parts removed; Fig. 3 is an enlarged transverse section taken on the line 33 of Fig. 1; Fig. 4 is a sectional-view taken transversely of the joint between a stile and a rail, and on the line 44 of Fig. 1; Fig. 5 is a perspective view showing the method of interlocking the uniting key with the stiffening channel, the parts being slightly separated; Fig. 6 is a perspective view of a portion of a stile coped to receive rails; Fig. 7 is a perspective view of a portion of the glass molding and glazing strip;

and Fig. 8 is a sectional view showing a" single thin sheet panel construction for rails or stiles.

Referring to the-drawings 10 and 11 designate the stiles of the door or panel and 12 and 13 designate the top and bottom rails which are united to the ends of the stiles.

Referring to Fig. 6, each of the stiles is made of sheet metal and has an end 11 and parallel sides 15. At the upper and lower .ends of each stile the sides 15 are bent inwardly as at 16 to provide flanges which fp im shoulders on the interior of the hollow s 1 e.

Between the flanges 16 at the opposite ends of the stile the sides 15 are bent inwardly as at 17 to form shoulders on the interior of the stile which are in fact a continuation of the shoulders 16 at the ends of the stile, whereby a substantially continuous shoulder is formed on each side 15 throughout the length of the stile. A beveled or ornamental molding 18 is formed at the free edge of the shoulder 17 and integral with the sides 15. The molding 18 extends inwardly and its free edge is bent outwardly as at 19 to provide a locking groove 20 at the outer end of the moldings on the side members 15. In Fig. 6 the grooves are shown as opening outwardly, but it will be understood that they may also be formed to face each other as shown in the upper part of Fig. 2.

A stiffening channel 21 shown in perspective in Fig. 5 is designed to fit between the sides 15 of the stile, being provided with parallel flanges 22 at its free edges which engage the inner surfaces of the side walls 15. The stiffening channel is formed from a single plate of sheet metal and is bent to provide a depressed portion or channel 23 extending longitudinally thereof at its center. The side walls 21 of the channel have laterally extending flanges 25 which fit against the shoulders 17 and hold the channel in place. The channel is inserted into the stile through the end of the latter and it spans the space between the side walls 15.

A key 26 unites the channel and the outer ends of the moldings 18. Asyshown in Fig. 5 the uniting key comprises a single metal plate shaped so as to form a substantially rectangular central portion, the base 27 of which has the oppositely disposed tongues 28 struck therefrom. The tongues 28 are constructed to fit into slots 29 in the bottom 30 of the channel on the stiflening member 21. The parts 21 and 26-are fastened together by fastening the tongues 28 into the slots 29 and bending the tongues in opposite directions thereby preventing relative movement between the two and securely uniting the stiffening channel and key. The base 27 of the key is of such width as to fit snugly into the channel 23 and the side walls 31 fit against the sides 24 of the channel. The key has two spaced parallel walls 32 which are. joined to the walls 31 by the shoulders 33. The outer free ends of the walls 32 are provided with flanges 34 which extend outwardly and at the outer ends of the flanges 34 the metal is bent rearwardly parallel to the walls 32 as at 35 and then inwardly as at 36 whereby grooves 37 are provided to receive the edges of the'fianges 19 at the sheet metal plates 39 provided with flanges 40 at-their edges which extend beneath the shoulders 33' and serve to retain the panel in position.

When glass panels are used a panel molding is provided which is illustrated in perspective view in Fig. 7 and consists of two plates. The glass molding strip has a base portion 41 shaped similar to the base of the uniting key 26, but smaller so that it will slide into the base of the uniting key. The shoulders 42 on the glass molding strip engage againstthe shoulders .33 of the uniting key and the molding strip is thereby locked in place.

Two parallel faces 43 and 44 are formed at the inner edges of the shoulders 42 and are spaced apart and when in position they engage against the parallel faces 32 of the uniting key. The outer edge of the face 43 has an outwardly extending flange 45 whichwhen in position is spaced from one of the flanges 34 on the uniting key and the flange 46 at the inner end of an adjustable glazing strip 47 is clamped between the flange 45 and the adjacent flange 34. The flange 46 on the glazing strip 47 constitutes one side of a groove at the inner edge of the glazing strip, the other sideof the groove being designated by the numeral 48 and being somewhat shorter than the flange 45 leaving a shoulder 49 at the inneredge thereof to support the glass panel 381. At its outer free edge the glazing'strip has a bead 50 and between the head 50 and the wall 48 there is a flat part 51 which fits against one side of the glass panel. The face 44 of the glass molding fits against the opposite side of the glass panel and has a bead 52 at its outer end located opposite the bead 50 on the glazing strip. The glazing strip and glass molding are only spaced apart a distance suflicient to receive the glass panel and will provide a rigid supporting and retaining means for the panel.

In Fig. 8 we have shown a modified form of device for retaining a single sheet panel 382 in place. Theadapter for the panel 382 comprises a sheet metal member which has a channel 53 extending longitudinally thereof and located midway between its sides. The plate on the opposite side of the channel is bent upon itself to provide the rearwardy extending legs 54 of the adapter and the free ends of the members 54 are bent upwardly at an angle as at 55. The upwardly extending parts 55 of the adapter engage the shoulders 33' of the uniting key 26 to lock the adapter to the stile. The panel 382 may readily be forced into the channel 53' when the parts have been assembled. A gasket may be inserted in the interior grooves provided by the beads 50 and 52 to frictionally engage the glass panel. I

Referring to Fig. 4 the side walls 57 of the rails are bent at their ends to form the inwardly extending portions 58 and .the rearwardly extending portions 59 to provide hooked portions at the ends of the side walls to receive the hooks 60 on the rail-hooks 61 which have laterally and inwardly extending flanges 62 constructed to fit against the flanges 25v at the lower ends of the stiffening member 21. The flanges 62 of the railhooks are provided with slots corresponding to the slots 29 of Fig. 5 to receive the tongues 63 punched from the faces 25 of the stiffening channeL21. The free ends of the tongues 63' are bent against the outside faces of the portions 62 to connect the railhooks and stiffening channels and thereby unite the rails and stiles. The rail hooks 61, 61 and the slotted base portions 62 thereof are made from a single piece of sheet metal. The flanges 16 abut against the inwardly extending portions 58 on the ends of the .rails and a close fitting joint is there by provided between the rails and stiles.

It will be understood that the joint between the rails and stiles shown in Fig. 4

is duplicated on the opposite end of the rail. As shown in Fig. 2 the upper edge of the rail 13 and the lower edge of the rail 12 is constructed in the same manner as the panel supporting edge of thestiles heretofore described and there will therefore be no need of repeating the description of the construction shown. The top and bottom edges of the hollow stiles and rails may be closed by means of a channel member 65 and plate 66 which are suitably secured in the open ends.

While we have shown and described the construction in detail it will be understood that we do not wish to be limited to the between said bracing member and key member.
